Design Summary -------------- Design Summary: Number of errors: 0 Number of warnings: 0 Logic Utilization: Number of Slice Flip Flops: 131 out of 9,312 1% Number of 4 input LUTs: 112 out of 9,312 1% Logic Distribution: Number of occupied Slices: 118 out of 4,656 2% Number of Slices containing only related logic: 118 out of 118 100% Number of Slices containing unrelated logic: 0 out of 118 0% *See NOTES below for an explanation of the effects of unrelated logic. Total Number of 4 input LUTs: 140 out of 9,312 1% Number used as logic: 112 Number used as a route-thru: 28 The Slice Logic Distribution report is not meaningful if the design is over-mapped for a non-slice resource or if Placement fails. Number of bonded IOBs: 34 out of 66 51% IOB Flip Flops: 27 Number of RAMB16s: 4 out of 20 20% Number of BUFGMUXs: 1 out of 24 4% Average Fanout of Non-Clock Nets: 2.51 Peak Memory Usage: 367 MB Total REAL time to MAP completion: 2 secs Total CPU time to MAP completion: 2 secs NOTES: Related logic is defined as being logic that shares connectivity - e.g. two LUTs are "related" if they share common inputs. When assembling slices, Map gives priority to combine logic that is related. Doing so results in the best timing performance. Unrelated logic shares no connectivity. Map will only begin packing unrelated logic into a slice once 99% of the slices are occupied through related logic packing. Note that once logic distribution reaches the 99% level through related logic packing, this does not mean the device is completely utilized. Unrelated logic packing will then begin, continuing until all usable LUTs and FFs are occupied. Depending on your timing budget, increased levels of unrelated logic packing may adversely affect the overall timing performance of your design. Mapping completed.
